To all whom it mag/concern.-

Be it known that we, ROBERT JOHN HMATHIspitizens residing stForrest City, in the which the followmg is a, specifi This invention relates, to cer 1 o useful improve meets inhehgeroccplin 1 ingsfor screw co'sve'yers.

In oil-mills there is invsri spiral conveyors, generally of for unloadicg seed. or other material from cars, and other storegepcints and for transferring the said material ,to. the mill. The conveyers ere generellyoperetcil simuh one power source.

The hanger l3.is or may be integral with and suspended by means of a cross-bar 14. The latter'is adapted to slidein opposite directions upon the bearing-plates 15, one of which is secured opposite to the other upon the topof the casing or box- 1 by means of the headed bolts 16. Each of the latter extends upwardly through a rectangular slot 17, formed near the ends of the cross-bar l4, and have interposed between the heads thereof a'ndthe bar 14 the washers 18. The bolts 16 connect the crossbar to the top of the casing in such-a manner as to permit the bar to move {longitudinally in either direction. The slots 18-are of such length as topermit this longitudinal movement in either directionof the cross-bar 14 as well as a like movement to be imparted to the hanger 13 to cause the'operation of the clutching-sleeve 8 in the manner as hereinbefore referred to.

The reference-numeral 19 denotes a yoke, which has its lower portion surrounding and engaging as well as supporting the cap 13. The upper end of the yoke extends through the top of the hanger and cross-bar 14 for connecting or securing the cap 13' to the hanger 13. The yoke is secured to the crossbar 14 bymeans of the fastening-nuts 20, mounted upon the screw-threaded ends 21 of i the yoke. The hanger 13 is provided with a passage or port 22, which registers with an sleeve when the hanger is operated.

The construction ,hereinbefore described ;not only provides a means for disconnecting and connecting the power to the conveyer shaft, but also forms a bearing for the shafts through the medium of'the journal-stud 7, and, further, provides a means for supporting'the said shafts within the conveyor casing or box. By the foregoing arrangement and construction of the various parts it is obvious that when it is desired to discontinue the operation of the conveyor-shaft by slidopening in the cross-bar to receive a lubricant for 'suitably lubricating the clutchinging the hanger toward the power-shaf t the clutching-sleeve will disconnect from the conveyor-shaft, and consequently the latter will cease to revolve. Itwillbe evident that from the construction hereinbefore described a bodily-movable hanger coupling-bearing is provided. The outer ends of the power and conveyer shafts may be supported in suitable journals, (not shown,) or the conveyor, as well as the power-shaft, may be provided with suitable bearings throughout their length; but as this does not form a portion of our invention it is thought unnecessary to show and describe a bearing means for the shafts. The outer ends of the power and convcyer shafts may, if desired, be journaled in the end walls of the casing; but as this forms no portion of our invention it is thought unnecessary to describe and show the same.

his thought the many advantages of con screw conveyors in the manner as set forth can be readily understood from the foregoing description, taken in connection with the accompanying drawings, and it will also be 'structing a hanger coupling bearing for .v

noted that minor changes may be made in the details of construction without departing from the general spirit of our invention.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-- 1. The combination with a power and a conveyor shaft, of a journal-stud secured to the power-shaft and extending into the conveyershaft, a clutching-sleeve engaging with said journal-stud and with the conveyor-shaft for connecting the latter to the power-shaft, and a bodily-movable hanger for supporting the said shafts and for operating the said sleeve.

2. The combination with a power and a conveyer shaft, of a journal-stud secured to the power-shaft and extending into the conveyorshaft, :1. clutching-sleeve engaging with said journal-'studand with the conveyor-shaft for connecting the latter to the power-shafta pair of collars mounted on said clutchingsleeve, and a bodily-movable hanger for supporting the said shafts and engaging with said collars'foroperating the said sleeve.

3. The combination with a power and a conveyer shaft, of a journal-stud secured to the power-shaft and extending into the conveyorshaft, a clutching-sleeve mounted upon; said journal-stud and with the con'veyer-shaft for connecting'the latter to the power-shaft, a pair of collars mounted on said clutchingsleeve, clutching-sleeve to the journal-stud, and a bodilymovable hanger for supporting the said shafts and engaging with said collars for operating the said sleeve.

4. The combination with a conveyor-casing and a power and a conveyor shaft arranged therein,of a journal-stud carried by the powershaft and-adapted to extend into the conveyorshaft, a clutching-sleeve mounted upon and cngagin with the said journal-stud, a pair of a spline for suitably connecting the collars mounted upon said sleeve, a hanger for supporting said sleeve and arranged between the said collars, said hanger adapted to be moved for causing the engagement and the disengagement of the conveyer-shaft with the power-shaft, and means adapted to slide upon the casing andconnected to said hanger for suspending and operating the same.

5. The combination with a conveyer-casing and a power and a conveyer shaft arranged therein,of a j ournal-stud carried by the powershaft and adapted to extend into the conveyershaft, a clutching-sleeve mounted uponand' engaging with the said journal-stud, a pair of collars mounted upon said sleeve, a hanger for supporting said sleeve and arranged between the said collars, said hanger adapted to be moved for causing the engagement and the disengagement of the conveyer-shaft with the power-shaft, means adapted to slide upon the casing and connected to said hanger for suspending and operating the same, and a yoke for connecting the hanger to said suspending means therefor.

6. A hanger coupling-bearing for a power and a conveyer shaft consisting of a journalstud carried by the power-shaft and adapted to extend into the conveyer-shaft, a clutchingsleeve rotating with the journal stud and capable of longitudinal movement While revolving, said clutching-sleeve adapted to engage with the conveyer-shaft for connecting the same to the power-shaft, a vertically-extending hanger for supporting and operating said clutching-sleeve, a collar mounted on the clutching-sleeve at each side of the said hanger and engaged by the said hanger for operating the clutching-sleeve, a cross-bar provided with slots to permit of a longitudinal movement, and a yoke engaging the hanger and extending through the cross-bar for connecting the hanger to the said bar.

7. In combination, a power and a conveyer shaft, clutching means for connecting said shafts together, a bodily-movable hanger for supporting said shafts and clutching means and adapted when moved to suitably operate said clutching means, and means for suspending said hanger.

8. In combination, a power and a conveyer shaft, clutching means for connecting said shafts together, a bodily-movable hanger for supporting said shafts and clutching means and adapted when moved to suitably operate jsaid clutching means, means for suspending said hanger, a cross-bar provided with a slot in each end, and means for connecting said hanger to said cross-bar.

9. Ahanger coupling-bearing for conveyershafts consisting of a clutching-sleeve, a bod ily-movable hanger for operating and supporting said sleeve, and means for suspend ing and operating said hanger.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
